The lowest salary is $42,000 a year--for jobs like receptionist, staff assistant, and "analyst". The highest paid staff are pulling in $172,000 a year, and there are quite a few of them.
Not only that but according to Politico, the presidential staff is growing:
A quick review found the White House payroll appears to have grown since last year, going from $37.1 million in 2011 to $37.8 million in 2012. The number of employees listed also grew -- from 454 last year to 468 in 2012.
